Using Accessibility Features

What are Accessibility Features?

The accessibility features in Oracle BI EE aim to make aspects of navigating and using the product easier for persons with disabilities and for the aging population. The accessibility features support the use of standards-based assistive-technology hardware and software (such as Freedom Scientific JAWS or Microsoft Narrator). The accessibility features are grouped into these general categories:

• Features used by third-party assistive-technology products. These features center on providing a user interface that consists of standard HTML elements that can be easily interpreted by third-party assistive technology products.

• Accessibility mode, as described in "Changing to Accessibility Mode."

• Keyboard shortcuts that make it easier to navigate content for users with limited or no ability to use a mouse.

  For information, see "Keyboard Shortcuts."

• Content design capabilities that make it possible for content creators to create content that supports users with accessibility needs. While Oracle BI EE provides accessibility mode that offers many features automatically, you as the designer must create content that meets the accessibility requirements of your user community.

  For information, see "Designing for Accessibility" and "Using Objects to Enhance Accessibility."

Signing In Using Keystrokes

Use the following procedure to sign into Oracle BI EE using keystrokes rather than the mouse.

To sign into Oracle BI EE using keystrokes:

1. In a browser, display the Sign In page for Oracle BI EE.

2. If you want to change the language that Oracle BI EE uses, press Tab to place the insertion point in the Language field and use the arrow keys to select the desired language. The insertion point is then placed in the User ID field.

3. Enter the ID and press Tab to place the insertion point in the Password field.

4. Enter the password.

5. Perform one of the following actions:

   • If you want content for Oracle BI EE to be rendered in a browser in a way that facilitates the use of a screen reader or want to change the language that Oracle BI EE uses, press Tab twice to place the insertion point in the Accessibility Mode box.

   • If you are ready to complete the sign-in process, then press Enter to activate the Sign In button.

6. If you want content for Oracle BI EE to be rendered in a browser in a way that facilitates the use of a screen reader, press the spacebar to select the Accessibility Mode box.

7. Press Shift+Tab twice to place the insertion point on the Sign In button, then press Enter to activate the Sign In button.

Changing to Accessibility Mode

Accessibility mode in Oracle BI EE makes the rendering of the user interface more compatible with screen readers while allowing only that functionality that is supported for users with disabilities to be visible. The following list provides information on accessibility mode:

• The "BI Composer wizard" is displayed in place of the "Analysis editor." For more information on BI Composer, see Chapter 14, "Using BI Composer to Work with Analyses."

• The Home page does not contain links for accessing the Administration page or for performing most editing functions, such as for editing dashboards.

• Graphs and map views are not displayed but are instead converted to one or more annotated tables.

• Tables and pivot tables are rendered with appropriate internal annotations to enable screen readers to describe the contents of cells.

  Refer to your assistive-technology documentation for all applicable table navigation shortcuts.

• You cannot use the mouse to modify the layout of a table or pivot table.

• Performance tiles, and treemaps are rendered as pivot tables.

• The collapse icon is included in the upper-left corner of each section on a dashboard page, even if that section is marked as not collapsible in the Dashboard builder. This allows the icon to be the first element that receives focus when using the keyboard to navigate on a dashboard page.

• The Page Options toolbar button on a dashboard page, which displays a menu of page options, is not available.

• If the dashboard page is refreshed, even if you navigate to another page, then the location of the focus is not preserved. You must press Tab to navigate through the focusable items.

• Trellis views, when displayed on dashboards, are converted to pivot table views with the following changes:

  • Attribute columns of the inner graph are not included in the pivot table views.

  • Measure values are aggregated to the new grain of the pivot table views.

By default, Oracle BI EE does not use accessibility mode. Each user can decide whether to enable accessibility mode during sign in as described in "Signing In Using Keystrokes" or after sign in by using the following procedure.

To enable accessibility mode using keystrokes after sign in:

1. Press Tab multiple times to navigate through the global header, until the focus is on your user name in the Signed In As area.

2. Press Enter, then Tab to highlight the My Account link.

3. Press Enter to display the "My Account dialog."

4. Press Tab to select the "My Account dialog: Preferences tab."

5. Press Tab to navigate through the fields on the tab until you reach the Accessibility Mode options.

6. Use the arrow keys to select the On option.

7. Press Enter to save your changes and close the dialog.

8. Refresh the page to see it displayed in accessibility mode.
